Abstract: An unstructured hybrid mesh numerical method is developed to simulate open channel flows. The method is applicable to arbitrarily shaped mesh cells and offers a framework to unify many mesh topologies into a single ...

Abstract: Distributed watershed modeling has gained popularity in recent years. Prevalent models in the United States include CASC2D and WEPP, among others. Although the existing models have been successful for some applications, a ...

Abstract: A two-dimensional layer-averaged model is developed and verified to simulate turbidity current characteristics and its sluicing in reservoirs. The governing equations consist of mass and momentum conservation laws for the ...

Abstract: A three-dimensional computational method, without the use of hydrostatic assumption, is developed to solve fluid flows for hydraulic applications. Numerical algorithms and verification of the nonhydrostatic model are ...

Abstract: A three-dimensional numerical method, without the hydrostatic assumption, is developed to solve flow problems in hydraulic engineering. This method adopts an unstructured grid technology that is applicable to arbitrarily ...

Abstract: An open-channel junction flow is encountered in many hydraulic structures ranging from wastewater treatment facilities to fish passage conveyance structures. An extensive number of experimental studies have been conducted ...

Abstract: Many rivers in Taiwan have steep slopes, are subject to typhoon-induced flood flows, and contain soft bedrock that is exposed at many locations and easily erodible. The occurrence of extensive bedrock erosion has been a ...

Abstract: A two-dimensional (2D) layer-averaged model was previously developed to simulate turbidity current characteristics and its sluicing in reservoirs. It was calibrated and validated using the data from a down-scale physical ...
